BACKGROUND OF THE INVENTION

The present invention relates to coffee makers and in particular to acoffee maker utilizing a stream of hot water through tamped groundcoffee.

Coffee is generally prepared in a coffee maker by measuring an amount ofground coffee into a coffee filter, closing a lid over the groundcoffee, and providing a stream of hot water through the loosely packedground coffee. Unfortunately, water passes freely through the looselypacked ground coffee and does not obtain the full flavor which mightotherwise be obtained.

U.S. patent application Ser. No. 12/610,181 filed Oct. 30, 2009 for“Self Tamping Coffee Holder” discloses a coffee making apparatus andmethods which provide a tamped packing of loose ground coffee therebyobtaining richer flavor. The coffee maker includes a reservoir, a pump,a heater, and a check valve. Coffee grounds are first loosely depositedin a coffee holder and then tamped onto a compacted state. The coffeeholder may be filled loosely with the coffee and then placed into thecoffee making apparatus and compacted, or the coffee may be compacted inthe coffee holder and then the coffee holder placed into the coffeemaking apparatus. The compacting may be by a spring or by a resilientsolid material and may be part of the coffee holder or part of thecoffee making apparatus.

Further, U.S. patent application Ser. No. 12/620,584 filed Nov. 17, 2009for “Self Tamping Coffee Holder” discloses a self-tamping coffee holderwhich tamps loose ground coffee obtaining richer flavor. The coffeeholder includes a holder base and a holder cap. Coffee is looselydeposited in the coffee holder and the holder cap is attached to theholder base. An internal filter chamber holds the coffee and allowstamping of the coffee into a compacted state. The filter chamber may beformed by a fixed filter or by a removable filter constructed of filterpaper, nylon mesh, metal mesh, or any material capable of holding thecoffee while allowing a flow of heated water through the coffee. Thetamping may be by a spring or by a resilient solid material attached tothe coffee holder and may push the coffee down inside the filter or pushthe filter and the coffee up against the holder lid. While the '181 and'584 applications disclose tamping coffee, they do not disclose avariety of embodiments of cooperating coffee holders and coffee makersfor tamping.

BRIEF SUMMARY OF THE INVENTION

The present invention addresses the above and other needs by providing acoffee maker and coffee holder which cooperate to tamp coffee in thecoffee holder. The coffee holder may include a top tamping spring, abottom tamping spring, or a top or bottom passage allowing entry of atamper into the coffee holder. The coffee maker includes an actuatorabove or below the coffee holder, or a fixed tamper attached to aceiling or platform of the coffee maker. The coffee holder may beinserted between the ceiling and platform, or into a moving drawer ofthe coffee maker. The actuator may be a solenoid actuator, or ahydraulic actuator actuated by water pressure of heated water used forbrewing.

A fourth coffee maker 10 d having a third holder base 31 c for receivinga packet 41 a containing untamped coffee, a knife 50 for cutting thepacket 41 a open, and tamping spring 36 under the holder base 31 caccording to the present invention for tamping the coffee when thecoffee maker lid is closed is shown in FIG. 39A, the fourth coffee maker10 d with the holder base 31 c holding the packet 41 a of untampedcoffee is shown in FIG. 39B, and fourth coffee maker with the holderbase 31 c holding the packet of tamped coffee 41 c with the coffee makerlid 14 closed to push the holder base down over the tamping spring 36for tamping the coffee is shown in FIG. 39C. The coffee maker 10 dincludes a somewhat pointed nozzle 19 a to puncture the packet 41 a toprovide the flow of hot water to the tamped coffee in the packet 41 a.Known coffee packets include internal filters to allow a flow of hotwater through the packet to make the coffee drink while preventingcoffee grounds from escaping. The cut in the packet 41 a made by theknife 50 allows the coffee drink to escape from the packet while filtermaterial in the packet 41 a prevent coffee grounds from escaping. Thetamping spring 36 may also be attached to the lid 14 as in FIGS.38A-38C.

The packet 41 a may be an air tight pod containing coffee in filterpaper and positioning the knife on the side of the holder base 31 cresults in less likelihood of the knife 50 cutting the filter paper. Thepacket 41 a is preferably airtight to maintain coffee freshness and maybe plastic, metal foil, or other airtight material which is sufficientlyflexible to allow the coffee contained in the packet 41 a to be tamped.Alternatively, the knife 50 may be eliminated when the packet 41 a isconfigured to burst under pressure to expose the coffee, for example,when the coffee maker tamps the coffee, the packet 41 a also bursts. Inone embodiment, filter paper 41 is inserted into the holder base 31 cwithout the knife 50, and the packet 41 a bursts during compacting torelease the coffee into the filter paper.

Known coffee makers use a sealed cup or capsule having a somewhat ridgedcup with a foil cover. Such cups might be compressible and used in thecoffee maker 10 d, however, a similar cup or capsule having a lessridged cup which may be compressed in the coffee maker 10 d are moresuitable for use in the coffee maker 10 d to allow tamping of the coffeecontained in the cup or capsule.
